Composite state functionality with allow_mixing

Question

I'm trying to use composite state functionality with allow_mixing and running into some issues. It appears that you cannot use composite states and allow_mixing at the same time.

For example,

@startuml

state "A" as stateA {
    state B
}
@enduml

Renders without issue.

However,

@startuml
allow_mixing

state "A" as stateA {
 state B
}
@enduml

Gives a syntax error on line "state "A" as stateA {"

Additionally,

@startuml
allow_mixing

state "A" as stateA
@enduml

Renders without issue.

For context, I am trying to insert a table of conditions/information into a state or conditional of a state diagram. To achieve this, I am trying to mix json data into the diagram, but running into the issue above.

Is there a way to get allow_mixing to work with composite states? Or perhaps I am approaching the way I want to achieve a table/json data inside a state incorrectly?

You can now have this with last snapshot:

@startuml
state "A" as stateA
state "C" as stateC {
 state B
}
json foo1 {
  "foo2": "foo3"
}
@enduml

Hope this helps!

Thank you, that has solved what I was trying to do!

I can insert this json data like:

{
  "foo2": "foo3"
}

But, if my data is a list, like List<String> in java.

["foo2", "foo3"] 

I think this is also a kind of json data. But the plantuml show the error message.

Hi E.,

For that case, you must put all the list on a one-line, as:

@startuml
state "A" as stateA
state "C" as stateC {
 state B
}
json foo1_JSON_title  ["foo2", "foo3"]
@enduml

Enjoy,

Hi, Thanks for answer the question!

I use the Intellij Idea plugin named "plantuml4idea", the plantuml4idea's version is 6.4.0-IJ2022.2(because my idea's version on my computer is Intellij Idea 2023.1.3 Community Edition).

So if there is any version of plantuml4idea that can help me to insert "list" into the "state"?

thanks very much!

Hi E.,

Here is another example, with embedded JSON directly on State:

@startuml
state "A" as stateA
stateA : {{json%n()["foo2", {"f":1}]%n()}}
state "C" as stateC {
 state B
 B: {{json%n(){"foo2": [1 , 2, 3]}%n()}}
}
json foo1_JSON_title  ["foo2", "foo3"]
@enduml

Enjoy,
Regards,
Th.

Hi, thanks for the response! 

I found the reason about why I can not use 

B: {{json%n(){"foo2": [1 , 2, 3]}%n()}} 

in my idea.

My jetbrain idea's version is 2023.1 community, so I can only use the plantuml4idea[6.5.0-IJ2022.2]. This gramma doesn't work in this plugin version. and I can not change or update my jetbrains' version on my computer...

Also, I found my friend's jetbrain idea's version is 2023.3.2, He can use the plantuml4idea[7.13.0-IJ2023.2], and that can works on my friend's computer.

Can you help me to publish a new plantuml4idea version that can works on my intellij idea 2023.1 community? Thanks very very much !
